So... I've started a new campaign in BI as the Western Roman Empire (my first time as this faction).
However, I am playing with the intent to preserve the pagan religion and stamp out the new Christian menace.
The "disposal" of my Christian governors and leaders has not fared well for my popularity and neither has the destruction of all the Christian churches.
Some time into the game, i've lost almost all my control over mainland Europe and my main base of operations is in Britain.
I've only barely managed to avoid total bankruptcy through the capture and total destruction of Rome and other large rebel cities.

Has anyone else attempted to keep the Western empire 100% pagan? Is it even possible, or will i continue to get randomly Christian family members?
I've also never played as the Western Empire before so I don't know if the loss of all of mainland Europe to rebellion is something that is to be expected even without the supression of Christianity.
